Deciding which Eva Longoria look we prefer is like choosing between Lay's cheesy garlic bread and Lay's sriracha flavors. It just can't be done; they're both mouth-watering.

The actresses stunned in Cannes all weekend long. She donned a dramatic gold, long-sleeved, floor-length Zuhair Murad gown for the red carpet premiere of Le Passe on Friday evening and a Victoria Beckham summer dress while shopping yesterday afternoon. The gold gown also bared her sculpted back and tiny tattoo.

The fashion show continued into the night when the Lays spokeswoman wore a sheer black Yanina dress to the Global Gift Gala, followed by a bright orange Emilio Pucci top and shorts to the after party.

Despite her high marks at the festival, she slipped up on Saturday at the premiere of Jimmy P.: Psychotherapy of a Plains Indian. Even though her mint green Atelier Versace gown was gorgeous, its slit was a tad too high. The former Desperate Housewives star had a wardrobe malfunction while tugging up her hem to avoid getting it wet at the rainy premiere. She exposed herself with no underwear. They just never learn ...

Even though Eva Longoria has denied dating Ready for Love contestant Ernesto Arguello, we spotted them together a little over a month ago in these exclusive photos, and not only was he being totally chivalrous, but the two were holding hands!

Eva, who serves as an executive producer for the show, stepped out with the 33-year-old hottie on March 16 at Bootsy Bellows, and since then they've been seen at the Chateau Marmont, and several sites even report that he's crashing at her Los Angeles home! However, Eva's rep says the two are "friends" and the 38-year-old actress denied reports that she's dating Arguello, tweeting on Monday, "WHAT?! AGAIN? Sorry guys, still not dating Ernesto Arguello. Who are these 'sources?'" Um, we say the proof is in the pictures!

And you gotta admit ... these two would make a totally cute couple!

Since Eva Longoria and Mark Sanchez split back in October, the sexy Latina's romantic life seems to have been rather dry ...

But we have these EXCLUSIVE photos of Eva last night with a HOT new mystery man at Bootsy Bellows.

A source inside the club tells X17online, exclusively, "I don't know who that guy was, but he and Eva were flirting and laughing together the whole night. It seemed like she'd just met him and was excited to find a hot guy she could have fun with. Her girlfriends let him sit next to her the entire time and they all got along really well."

The tall-dark-and-handsome hunk led Eva by the hand to her car at the valet and left together, with some pals, including Pussycat Dolls' director Robin Antin, to continue their evening at Soho House.

The group partied late into the night and the just-turned-38 Eva was in high spirits. Looks like she may have gotten a new man for her birthday!

Eva Longoria loves to get her hair blown out by friend and celebrity hairstylist Ken Paves.

The former Desperate Housewives starlet rocked head to toe black while leaving Paves' Beverly Hills salon. Love that black Birkin bag!

Seems like Eva is always getting her hair done. At least she can call on her talented BFF to get the job done!

Eva Longoria helped announce the Lay’s Do Us a Flavor contest finalists during the opening bell at the New York Stock Exchange on Tuesday, and we're not sure if she sampled the chicken and waffles flavor, but she sure looks happy to be holding it!

Longoria and fellow campaign spokesperson, chef Michael Symon, introduced three new flavors that will hit shelves nationwide beginning next week. Fans have until May to vote for their favorites, and the flavor with the most votes will win the contest.

What are our other two options? Cheesy garlic bread and Sriracha, a hot sauce frequently used in Thai dishes.

Eva Longoria was spotted at a friend's house on Tuesday, and the former Desperate Housewives starlet was dressed to the nines when we snapped her sneaking in the back gate. What's this about?

Eva stars in a hot new ad for L'Oréal Paris Men Expert, and in the video clip below she flirts with a hunky male model, but the whole point is to encourage men to tone it down. "Hi, I'm Eva Longoria and being sexy isn't natural. We can't do all the work," she jokes in the video.

Eva has been a global ambassador with the company since 2005, but this is the first time a female spokesmodel has appeared in a L'Oréal Paris Men Expert campaign.

And not just any boot camp -- mixed martial arts boot camp! Perhaps Eva Longoria is getting in shape for a new film or TV role?

After working up a sweat, we spotted the former Desperate Housewives starlet stopping by Superfine Picture Company to collect some paperwork, which we're guessing is related to one of the two projects she's working on this year.

Eva is currently filming Frontera with Michael Pena and Ed Harris, which is about "a Sheriff in the U.S. tries to track down an illegal alien involved with a robbery that killed his wife," and after that she's set to begin work on Married and Cheating. But which film would she need to know MMA for? Maybe it's just for her?

As you know, Eva was at President Obama's inauguration in Washington, D.C. on Monday (she's a co-chair on the inaugural committee) and we asked her thoughts about Beyonce's lip synching controversy. While Eva didn't deny that the singer might have sung over a pre-recorded track, she definitely defended her! Check out what she had to say below:

Eva Longoria has had quite a busy week! Not only did she attend President Obama's inauguration, host the Latino inaugural event at the Kennedy Center over the weekend and attend a handful of parties in Washington D.C. but the former Desperate Housewives hottie has been carving a name for herself as a political activist.

Eva covered the front page of the Wall Street Journal last week and she also chatted with George Stephanopoulos on This Week to discuss the importance of changing immigration laws.

"I'm trying to do my part as a citizen and my part as a Hispanic and as a woman and as an American," she said. "So, you know, I enjoy it. I think everybody should be civically engaged in a level that would affect policy. That's the point; that's how our government is set up ... What I am hopeful about is that this administration--and particularly President Obama--sees that immigration is an economic issue. It's also, for me, a humanitarian issue. But if we approach it economically, we have to understand that we are dependent upon a labor in this country, specifically agriculture, to provide low-cost products, and they're jobs that nobody else -- nobody else is doing."
